We have been using squid in a reverse proxy mode for several weeks now and its been working well. Lately we have remote users that have a transparent proxy and users are getting hung when trying to access a particular page. Going thru cache.log and all I see for every connection is "ALLOWED", but do see lines line this: 2011/03/15 09:47:20| clientReadBody: start fd=48 body_size=97 in.offset=0 cb=0x450740 req=0x1cf9dd40 2011/03/15 09:47:20| clientProcessBody: start fd=48 body_size=97 in.offset=0 cb=0x450740 req=0x1cf9dd40 2011/03/15 09:47:20| clientProcessBody: start fd=48 body_size=97 in.offset=97 cb=0x450740 req=0x1cf9dd40 2011/03/15 09:47:20| clientProcessBody: end fd=48 size=97 body_size=0 in.offset=0 cb=0x450740 req=0x1cf9dd40 2011/03/15 09:47:20| The reply for POST http://IP_ADDRESS/services/forward/jcore_security_check is ALLOWED, because it matched 'all' Not sure if clientProcessBody is a problem or not? Another group wants to replace the squid with Apache reverse proxy and tried it out this morning and it didn't have any problems with the remote user and the downstream proxy server.
